Gemstone Caverns

Legendary Land

If Gemstone Caverns is in your opening hand and you're not playing first, you may begin the game with Gemstone Caverns in play with a luck counter on it. If you do, remove a card in your hand from the game.

Tap: Add (1) to your mana pool. If Gemstone Caverns has a luck counter on it, instead add one mana of any color to your mana pool.

Gemstone Caverns Discussion

fifthdawn on Kynaios and Tiro, Defenders of Rainbow Vale

MEAT_TORNADO, also, Hall of the Bandit Lord works with the themes because not only does it enable Captain Sisay to tap right away, but it is also legendary itself, allowing me to find it with Captain Sisay. The life loss is mitigated somewhat by Riftstone Portal, Chromatic Lantern and Prismatic Omen. The upside of having powerful legends with tap abilities that allows me to get maximum value with Minamo, School at Water's Edge sometimes runs into the downside of needing a full turn to be able to use.

Especially with EDH being such a fast and powerful format now a days, you often lose your babies before they lose summoning sickness! So the Hall of the Bandit Lord really fills a real need for this deck. Plus, with so many ways to untap lands, i.e. Deserted Temple, Kiora's Follower, and Voyaging Satyr present, even if I need to activate it on the turn it enters, I still have several ways to do that.

Also, there is an increased emphasis on early colored sources of mana to enable Kynaios and Tiro of Meletis to arrive a turn or two early. I'm even theoretically able to cast the commander on turn one by exiling a card from my hand to start the game with a Gemstone Caverns in play with a luck counter, then playing a land for my turn, playing a Mox Diamond and discarding a land, and finally exiling Simian Spirit Guide. If the last card in my hand is a land, then on turn one, I will be on three lands, four colored sources including a mox, and I will have even drawn an additional card. If the card drawn is Jace, the Mind Sculptor, you have turn one Kynaios and Tiro of Meletis, turn two Jace, the Mind Sculptor... and that's living the dream!!

The nice part about Simian Spirit Guide being a fast mana source is it can be discarded to Survival of the Fittest if no longer needed, whereas the Mox Diamond cannot, although that has its own advantages of being able to recur the land with Crucible of Worlds. Also, Gemstone Caverns? Just so happens to be legendary. "My name is Captain Sisay, and I approve this message!!"

But then again, what do you expect from someone who has been playing this deck for more than five years now, having previously built it around Horde of Notions with a small elemental theme (Reveillark, Mulldrifter, etc) with no black spells because there was no four color commanders. Only black in the deck was for Volrath's Stronghold. :) :)

Those are good points. I agree you list probably doesn't fold to a single stax piece but I was being a bit hyperbolic. Sorry. Most stax lists run quite a few and if they only run the powerful ones then it only takes a couple to become oppressive.

Also have you considered Gemstone Caverns, I think the card is amazing for a combo list.

I can see the argument for Winds of Change actually. Would Liliana of the Veil be too midrangey for this list?

How has Waste Not performed for you?

Thanks so much for your feedback and suggestions! I totally agree with you on the Gemstone Caverns and will be adding a copy into the mainboard. Great idea! As for Goryo's Vengeance I have considered it but decided against it because it is a target for cascade. which can interfere with the consistency of the deck. For example: I need to cascade into breaking so I can mill crreatures into my Graveyard , then I hit vengeance instead and have no creaures to return). Haunted Dead is very interesting though I will def consider. Thanks again! Leave an upvote if you like the idea!

Ok, I was supposed to post on this deck when I posted mine, but one of my kids got sick and the cleanup process kinda.... Well, you know, I forgot what I was doing haha. I really like the deck, the biggest suggestion I could add to a deck like this where comboing off as quickly as possible is key, would be Gemstone Caverns. I run 2 in my dredge deck mainboard and let me tell ya, a turn 1 cathartic reunion into 3 grave trolls is pretty OP. The great thing about Caverns is that you can always either mainboard it or sideboard it in your deck, and in game 2 you always know exactly whether it's worth bringing in or coming out. The ability to tap for all 5 colors is great too provided that you get one in opening hand. Also, this deck is just SCREAMING for Goryo's Vengeance but I am sure you considered it already. It's not exactly a cheap card to acquire, but it would be awesome. If the Thirst for Knowledge is more important for it's discard, maybe Haunted Dead would be a more consistent option? You also get 2 creatures on board and still get to discard 2 cards for 1 mana less and not counterable (unless you play the guy with 4 voidslime and 4 squelches mainboard lol). Most importantly it can do it from the graveyard, so no worrying about a Thirst for knowledge getting milled in when you needed it... Also the CMC is 4 so it would be less likely to be cascaded into than Thirst.

Add this:

Polluted Delta - In colour fetch land, why would you not?

Mana Confluence - Only slightly worse than City of Brass (actually better against port)

Elves of Deep Shadow - Replace one of the other elves. Helps cast leovold on 2.

A Doomsday package - I know it's what every cEDH leovold deck does but that's because it's insane (usual package is something like Gitaxian Probe, Predict, Laboratory Maniac, Unearth, Street Wraith)

Arcane Denial - One of the best counterspells in edh just gets better with leo in play.

Spell Pierce - Fantastic counterspell

Steel Sabotage - Very debatable, can be used as a ritual with vault or crypt, has targets against almost every deck.

Mental Misstep is surprisingly great

Dismember - 1 mana, kills everything.

Ad Nauseam - The best card in EDH

Carpet of Flowers - is actually nuts

Force of Will - cEDH is very, very, combo heavy making force an important inclusion in pretty much any blue deck.

Nature's Claim/Natural State - You have 0 ways to deal with a resolved artifact and this deck rolls over pretty hard to Null Rod. Play your preferred one, or both.

Cut this:

Gemstone Caverns seems really awful, yes sometimes you'll get to drop leovold a turn sooner off it but even then you end up down a card right off the bat, and then 93% of the time it will just make your mana worse. That's not even counting the times where you go first...

Voidslime is also miserable, it's pretty hard to cast costing 3 coloured mana and the versitility doesn't make up for how much worse it is than Counterspell, Squelch or Stifle. Also strictly worse than that new card in AER (Disallow)

Prosperity is bad, even if leovold is in play you're still giving your opponents a card for free without taking anything from them, meaning to actually make card advantage you'd have to cast it for 5+ (assuming 4 players). Otherwise you're just putting yourself way behind.

Blightsteel Colossus is quite frankly useless in cEDH since metas are so combo heavy and most removal exiles anyhow. For this to actually be good you have to spend your whole turn casting it, have it resolve, have it survive until your next turn and then it still only kills one player/turn.

Lotus Bloom is just too slow. Same goes for Ashes to Ashes and Putrefy.

Grim Monolith you aren't playing storm, you aren't actually playing very many cards that can use 3C effectively and you aren't playing Power Artifact so this card doesn't actually do very much.

Twincast: Why is this even here?

Thought Vessel you run so many wheels that you shouldn't ever really have more than seven in hand, making Mind Stone strictly better.

Tolaria West doesn't have enough good targets, coffers urborg doesn't even seem that insane in this deck. Certainly not good enough to warrant playing an etb tapped land.

Worldly Tutor: Maybe I missed something but Teferi is the only creature worth skipping a draw to tutor for (most of the time).

Lightning Greaves: Again I might have missed something, but Teferi is the only creature that you care about giving shroud. (I guess blightsteel, but that sucks anyways)

Swiftfoot Boots is a bad greaves.

Thran Dynamo: If you really want a big mana rock play Gilded Lotus.

Gemstone Caverns if it's in your opening hand and there is something in your hand that isn't terribly useful is great mana acceleration, in that you start one mana a head of everyone else with one on field at the beginning of the game

I hate to rain on your parade, but I don't think that (and I could be wrong) exiling a spirit guide via Gemstone Caverns actually gives you mana. However, you cleared that problem up with Black Lotus, but if so then the opponent still loses on their first turn. I could also be wrong, though, so look into it.

sergiodelrio: all good. I think that yeah, 2x Gemstone Caverns makes a lot more sense.
